This is jasper fanclub for all we know we think she is dead but i got a theory if u do not like theory's then i am getting u 3 sec.
1 theory. There will be one episode were she is in the water looking dead then they will go close up to her face and her eyes will open at the end of a episode.
2 theory. The ruby's will come back and say SHE IS NOT THERE thrn lapis will go in the water then eventually find her almost bout to go to a regular gem with no body then when she comes up jasper will be coughing up water
3 theory. Jasperwas cought by another gem and was saved
4 theory.jasper never fell well kinda did but she did not what if a big stick caught her and when she wakes she will yell HEEEELP and the gems might help her
